"Life doesn't care about what you want. We don't get to choose."
―Teresa Mendoza

Teresa Mendoza is an exceptional survivor. A former money-changer from Sinaloa, she has risen to create and expand her own narcotics cartel, overseeing all cocaine transportation and distribution in Arizona and branching into Florida, Louisiana and Georgia.


Teresa was born in Culiacán and grew up in the Siete Gotas neighborhood, which she would later name her brand of tequila after. She was a salesgirl in the Buelna Mercado. She became a money changer at the age of fifteen, and by the age of sixteen she ran her own block2x01. She spent five years as a money changer on Calle Juarez1x02 before being picked up by Guero.

Her family was murdered by the cartels. Her mother was a nurse before she was born and used to say that "a bed is only as clean as its corners.2x01


She has long, wavy brown hair and is considered to be very pretty by all who meet her. Teresa has a scar hidden by her hair that she received after being punished by her boss for taking counterfeit bills while she was working in Sinaloa.

Teresa is often seen wearing shirts with three-quarter sleeves. She also keeps a necklace with the patron saint Malverde on it, but does not wear it.1x02

Teresa wears mainly white when she becomes the Queen as this color is supposed to protect her from her enemies.


Teresa is a survivor. She thinks quickly on her feet and does what it takes to make it out alive. Her alter ego, The Queen of the South, often appears to her and gives her advice when she is in dangerous situations, and she almost always follows it.

Teresa is resourceful and uses what is given to her, as proven when she uses any sort of weakness or distraction to her advantage. She is stubborn1x02 and wants to prove herself to Camila in order to keep herself safe. However, Teresa is also kind, as shown by the way that she deals with Tony, bandaging up Sandra's son,1x04 and by getting medicine for a girl with a fever.1x06 She fights for the people she loves, as evidenced by how far she goes to try to protect Tony and Brenda.

She doesn't want people to die when there's another way to do things -- like using the time she can see to get out of the cave.1x06 James thinks that this is impossible, but later joins her cartel hoping that it's true.3x02

She is hesitant to kill people, because that's not who she is. There are lines that she doesn't want to cross. She tries to save a man from being killed at Eric's party first by trying to free him then by flashing the headlights of James's car to try to distract Eric so that the man could escape. She is shaken by his death and calls Brenda telling her that she needs to get out of there.1x05

She doesn't like to do cocaine, refusing what is offered to her several times in the beginning. She also doesn't do coke with Leo, but is later forced to by La Capitana, and nearly overdoses.2x05 In Season 5 Teresa snorts cocaine to relieve stress.

She is good in numbers, observes more, talks less, can analyze a situation, and thinks fast. [1]

After Tony's death, Teresa understands that the only way to survive in this life is to be strong and ruthless. Teresa believes that if her operation becomes "too big to fail", she will be protected. Her goal is to become legit.


Teresa is good at math and can make calculations in her head. As she was a money changer in Sinaloa for five years, she can tell the difference between real and counterfeit money, which comes in handy when a customer tries to pay them in fake cash.1x03 She speaks both English and Spanish fluently and is very persuasive and can usually talk her way out of situations, making bold deals that leave both parties satisfied. Teresa talks less and listens more; she is reserved in her emotions, however she feels deeply for the people she cares about.
